BACKGROUND

1. Field

Apparatuses and methods consistent with the present invention relate toan air conditioner and more particularly to an air conditioner in whicha lower portion of a stand type indoor unit is supported by a framestructure and a main body is inclined backward at a predetermined angleso as to increase an air-blast distance of discharged cool air.

2. Description of the Related Art

In general, an air conditioner is configured with a compressor, acondenser, an expansion device, and an evaporator. An air conditionercools or warms indoor air using a refrigeration cycle of a refrigerantor purifies indoor air in order to promote a pleasant indoor environmentfor a user, and is largely classified into a separation type airconditioner and an integration type air conditioner.

The separation type air conditioner is configured by installing acooling device/heat sink in an indoor unit, installing a heatsink/cooling device and a compressor in an outdoor unit, and connectingthe indoor unit and the outdoor unit that are separated from each otherthrough a refrigerant pipe. The integration type air conditioner isconfigured by integrating cooling and heat-dissipating functions in asingle body and is disposed in a hole formed in a wall of a house or ina window by using a fixture.

Recently, a stand type air conditioner configured by installing anindoor unit on the floor so as to discharge air sucked in through asuction port via rotation of a fan through a heat exchanger has beenlargely used.

Such a conventional stand type indoor unit is put in the form of avertical cabinet on the floor, and a lower portion of stand type indoorunit is mainly used to suck in air, used to accommodate an air cleaner,or used for assembly of internal components.

Accordingly, the conventional stand type indoor unit has a large volumesuch that indoor spaces of a building may not be effectively used andalso does not provide a fine view due to uniform designs.

In addition, the conventional stand type indoor unit has a problem interms of a short air-blast distance of cool air since a main body isapproximately vertically put on the floor and sends cool air squarely.To overcome this, wind is adjusted in an upward direction using a bladeof a discharge port. However, a discharging direction of cool air and adirection of the blade do not match each other, and resistance isgenerated in air current that reduces intensity of the air blast, andthus there is a limit to sending cool air far.

In addition, for installation of the conventional stand type indoorunit, the connection pipe extends from the indoor unit to a wall surfaceand also a surface of the connection pipe is wrapped by a tape or thelike, thereby degrading an outer appearance.

The air conditioner 100 according to the present invention is configuredin such a way that the support B1 supports the main body M1 with a framestructure. Accordingly, although the same height as a conventional airconditioner is maintained, an open space may be formed in a portionbelow the air conditioner 100 so as to use a lower space, to easilyclean the floor, to achieve an excellent outer appearance, and to alsoallow an indoor space to look big.

Referring to FIGS. 2A and 2B, the front frame 140 is coupled to thefront portion of the cabinet 160 to support the main body M1 and thecabinet 160, and may further include a front frame cover 141. The frontframe 143 includes a case frame 143 a, a reinforcing member 143 b, alateral surface cover 143 c, a lower surface cover 143 d, a reinforcingframe 143 e, and a front frame coupler 143 f.

The front frame cover 141 is coupled to an upper portion of the frontframe 140 to cover the front frame 140 and the cabinet 160, therebyforming an external appearance of the air conditioner 100. The frontframe cover 141 may be coupled to the front frame 140 by a male andfemale coupler 141 a or a screw 141 c but is not limited thereto.

When the rear frame 150 does not include the horizontal frame 151 c,the pair of vertical frames 151 a and 151 b support the main body M1 andthe cabinet 160 with a column form. The rear frame cover 151 d forms therear frame pipe hole 151 f through which the pipe 170 passes.

In the air conditioner 100 according to the present invention, the frontframe 140 is inclined backward by as much as a preset angle α, and asthe front frame 140 is inclined backward, the main body M1 is alsoinclined backward by as much as an angle at which the front frame 140 isinclined. Accordingly, the air conditioner 100 according to the presentinvention may discharge cool air upward by as much as an angle β thatcorresponds to or is the same as the inclination angle α based on anaxis that is parallel to the ground so as to send the discharged airfarther than a vertically oriented conventional air conditioner, and adischarging direction of air corresponds to an inclination direction ofthe air conditioner 100, thereby minimizing friction of air.

An angle at which the air conditioner 100 is inclined backward may beequal to or greater than 1 degree or equal to or less than 9 degrees.For example, the inclination angle may be 3 degrees but is not limitedthereto.

The pipe hole 157 e is formed in any one of the coverplates 157 b and 157 c so as to externally extend the pipe 170. The pipe170 may extend from a lower surface of the cabinet 160, and in thiscase, the pipe cover 157 d may also be formed between a lower portion ofthe cabinet 160 and the rear frame 157 such that the pipe 170 is notshown in front of the air conditioner 100.

FIGS. 4A and 4B illustrate fourth and fifth modification examples of thesupport B1 according to the first embodiment of the present invention.The fourth and fifth modification examples are almost the same as thebasic configuration of the first embodiment illustrated in FIGS. 1A to2B except for a portion of the rear frame 150. In the fourth and fifthmodification examples, the same components as those of the firstembodiment are denoted by the same reference numeral.

FIG. 4A illustrates the fourth modification example of the support B1according to the first embodiment of the present invention. A support147 is configured without the rear frame 150 so as to support the airconditioner 100. The support 147 includes a pair of vertical frames 147a, a pair of horizontal frames 147 b, and a connection frame 147 c.

The pair of vertical frames 147 a is coupled to opposite sides of afront portion of the cabinet 160 and configured to incline the main bodyM1 backward at the same angle as a preset angle. The pair of verticalframes 147 a are formed at the front portion of the support B1 andconfigured by extending downward such that respective lower ends of thepair of vertical frames 147 a are connected to the pair of horizontalframes 147 b.

The pair of horizontal frames 147 b is connected to the lower ends ofthe pair of vertical frames 147 a, respectively and extends backwardfrom the lower end of each of the vertical frames 147 a. The pair ofhorizontal frames 147 b extends with a sufficient length so as to stablysupport the air conditioner 100.

FIG. 4B illustrates the fifth modification example of the support B1according to the first embodiment of the present invention. The fifthmodification example further includes a reinforcing member 147 e inaddition to components of the fourth modification example.

The reinforcing member 147 e may extend toward the connection frame 147c according to the fourth modification example from a rear portion ofthe cabinet 160 and may effectively support load concentrated on therear portion of the cabinet 160. In addition, an internal portion of thereinforcing member 147 e may be formed as a hollow so as to hide thepipe 170.

Hereinafter, an operation of the above configured air conditioner 100according to the present invention will be described in detail withreference to the drawings.

In response to power being applied to the air conditioner 100, acontroller (not shown) may transmit a control command according to adriving mode selected by a user so as to drive the air conditioner 100.

Along with rotation of the fan 125 formed in a fan unit 124, externalair is introduced through a suction port 113 formed in a rear portion ofthe air conditioner 100. In this case, the external air becomes cool airby adsorbing heat from the external air through the heat exchanger 129,and the cool air is discharged toward the front portion of the airconditioner 100 through the fan 125.

Since the main body M1 is inclined backward by as much as a presetangle, cool air is discharged upward based on an axis in parallel to theground at an angle corresponding to the above angle or at the same angleas the above angle. Accordingly, cool air is discharged farther than theconventional air conditioner so that the efficiency of the airconditioner 100 is increased.

The heat exchanger 129 generates condensation liquid water during heatabsorption, and the condensation liquid water is collected by a drainhose 129 and externally discharged through the pipe 170.

Referring to FIGS. 5A to 13B, components of a second embodiment arealmost the same as those of the first embodiment, except that a frame F2is perpendicularly put to the ground. In addition, the second embodimentmay have various configurations of a support B2, and thus a pipe 270 maybe configured in various ways. In the second embodiment, the samecomponents as those of the first embodiment are denoted by the samereference numeral.

In the second embodiment, the frame F2 is perpendicularly configured tothe ground and supports a main body M2 to be inclined. The main body M2is inclined backward by as much as a preset angle α. Accordingly, likethe air conditioner 100 according to the first embodiment, cool air maybe discharged upward by as much as an angle β that corresponds to or isthe same as the inclination angle α based on an axis in parallel to theground so as to send the discharged cool air farther than a verticallyput conventional air conditioner. In addition, a discharging directionof air corresponds to an inclination direction of an air conditioner200, thereby minimizing friction of air.

The angle α at which the air conditioner 200 is inclined backward may beequal to or greater than 1 degree or equal to or less than 9 degrees.For example, the inclination angle may be 3 degrees but is not limitedthereto.

With reference to FIGS. 5A to 6B, the air conditioner 200 according tothe second embodiment of the present invention will be described.
